Combining a sensitive photodetector and a Schmitt trigger, the CMOS TEKS6400 from Vishay Intertechnology is a lower-power alternative to the company’s existing bipolar TEKS5400. The sensor is designed for optical-shaft encoding applications such as drive-by-wire car steering, or peripherals such as printers and copiers. An integral spherical side-view lens provides ±30° angle half-sensitivity, along with an integrated daylight filter that is matched to the spectrum of IR emitters (950 nm), for interference suppression.
| Quiescent supply current is just 45 µA, from a supply of 2.5 to 5.5V, while operating temperature range is -40 to +85°C. The open-collector, logic-level output goes low when the photodetector is illuminated, and maximum output current is 20 mA. The 5×5×2.65 mm (high) component is priced at US$0.55 each, in 100,000 quantity. |
